Beverage Can's Top Having A New Stay-On-Tab For Opening Both A Drinking Hole And An Air Hole Thereon

Abstract

In an exemplary embodiment of the present invention, there is disclosed a beverage can's top having a new tab design which would be the tool that could allow for the opening of both the drinking hole and air hole in the can's top. The tab may have different shapes and sizes. The length of the tab may be varied to facilitate the efficiency of the opening. The locations of the air hole and drinking hole are within the range of the can tab.

What is claimed is: 
     
         1 . A beverage can's top having a new stay-on-tab opening mechanism comprising:
 a top plate of a beverage can;   a large frangible portion on the top plate defined by a scoring line partially severable from the top plate designed for liquid to flow out of the beverage can once severed;   a small frangible portion on the top plate defined by a scoring line partially severable from the top plate designed for air passage once severed;   a rivet fixedly attached to the top plate; and   a stay-on-tab designed to sever both of the frangible portions having a wide first end and a narrow second end, pivotally and rotatably secured to the rivet and coupled to the top plate via the rivet, the wide first end proximate the rivet and large frangible portion designed to sever the large frangible portion, the narrow second end proximate the small frangible portion designed to sever the small frangible portion.   
     
     
         2 . The beverage can's top having a new stay-on-tab opening mechanism of  claim 1 , wherein the narrow second end has a small tip smaller than the size of the small frangible portion. 
     
     
         3 . The beverage can's top having a new stay-on-tab opening mechanism of  claim 1 , wherein the rivet is located in the center of the top plate and is proximate the large frangible portion and distant the small frangible portion. 
     
     
         4 . The beverage can's top having a new stay-on-tab opening mechanism of  claim 1 , wherein the tab may have different shapes and sizes to enhance the functionality of the tab. 
     
     
         5 . The beverage can's top having a new stay-on-tab opening mechanism of  claim 1 , wherein the small frangible portion may be located on different positions relative to the large frangible portion as long as it is within the range of the tab. 
     
     
         6 . The beverage can's top having a new stay-on-tab opening mechanism of  claim 1 , wherein the rivet functions as a fulcrum for the tab to pivot about and the tab functions as a lever to facilitate opening of the small frangible portions, when the tab's wide end is lifted up, the tab's narrow end is tilted towards the small frangible portion and severs the small frangible portion of the top, creating an air hole. 
     
     
         7 . A beverage can's top having a new stay-on-tab opening mechanism comprising:
 a top plate of a beverage can;   a large frangible portion on the top plate defined by a scoring line partially severable from the top plate designed for liquid to flow out of the beverage can once severed;   a small frangible portion on the top plate defined by a scoring line partially severable from the top plate designed for air passage once severed;   a rivet fixedly attached to the top plate; and   a stay-on-tab having a first end with a small tip for severing both of the frangible portions and a second end for lifting up, pivotally and rotatably secured to the rivet and coupled to the top plate via the rivet, the small tip is smaller than the size of the small frangible portion.   
     
     
         8 . A beverage can's top having a new stay-on-tab opening mechanism of  claim 7 , wherein the rivet functions as a fulcrum for the tab to pivot about and the tab functions as a lever to facilitate the small tip to sever the large frangible portion when it faces the large portion and the tab is then rotated to have the small tip face towards the small frangible portion and function as a lever to facilitate the small tip to sever the small frangible portion. 
     
     
         9 . The beverage can's top having a new stay-on-tab opening mechanism of  claim 7 , wherein the tab may have different shapes and sizes to enhance the functionality of the tab. 
     
     
         10 . The beverage can's top having a new stay-on-tab opening mechanism of  claim 7 , wherein the small frangible portion may be located on different positions relative to the large frangible portion as long as it is within the range of the tab.
